Baseline Zuidwestelijke Delta: set-up and Calibration of model waqua-schelde_nevla-j07_5

The main objective of this study is to improve the predictive ability of the operational 2D NEVLA model for the River Scheldt. The geometry of the model is stored in an updated Baseline database. Baseline is set-up to automatically create inputs such as bathymetry and bottom roughness files for the hydrodynamic model. The model constructed out of Baseline is then calibrated automatically on bottom roughness with OpenDA, which consequently leads to a success with cost function reduced by 20%. The model validation shows that the model predictive abilities on water level, salinity and cross-sectional discharges are generally good.
